A stolen family heirloom is obtained by stealing artifacts from houses in the residential district in the Piscarilius House in Great Kourend. This must be given to Captain Khaled in exchange for 600-1000 coins along with thieving experience (appropriate to the player's thieving level) and 2% favour towards the Piscarilius House. According to Captain Khaled, the stolen artifacts are shipped overseas.

In order to help Captain Khaled with stealing artifacts, players require level 41 Thieving and 75% favour with the Piscarilius House.
